COX, OF ERIE, PENNSYLVANIA, ASSIGNOR T0' THE GILCHRIST COMPANY, OF NEWAR'K, NEW JERSEY, .A CORPORATION OF NEW JERSE-Y Ion-CREAM nrsnnn i Application filed November 13, 1925.

The invention relates to ice cream dishers.

In the operation of ice cream dishers of that type which comprises a scraper rotatable in a bowl andron an axis extending through the apex of the bowl, it has been found desirable to insure the separation of the ice cream from the bowl by imparting, besides the rotative shift of the scraper, an aXial shift to move the scraper away from the' wall of the bowl, and the object of the present invention is to provide a disher of this type in which provision is made for shifting the scraper in the aforementioned manner.

Other objects will appear hereafter from the detailed description.

The invention consists in the several novel features hereinafter set forth` and more particularly defined by the claims at the conclusion hereof.

In the drawing: Figrl is an inverted plan of a disher embodying the invention. Fig. 2 is a side elevation of the disher, parts being shown in section, on the line 2- 2 of Fig. 1. Fig. 3 is a sectional view, showing the mechanism for shifting the scraper axially, in its operative position. Fig. 4 is a section taken on line 4.-4 of Fig. 3. Fig; 5 is a detail perspective of the pinion and shaft for operating the scraper. Fig. 6 is a detail perspective of the plng in which the scraper-operating shaft is mounted;

The invention is exemplified in an ice cream disher comprising a bowl 10 of any suitable form,` and a handle-shank 11 which is provided at one end with a handle 12 and at its other end with an yintegral enlarged Vportion 13 having a seat 14 in which the bowl 10 is rgidly secured. scraper, for severing or separatingthe ice cream from the bowl and comprising a pair of arms or blades 15 and 16 which conform to the inner surface of the bowl, has its central portion fitting across the bottom or the apex of the bowl and has rigidly secured thereto a shaft 17: which is preferably riveted 'to the scraper, as at 18.

Serial No. 68,755.

Shaft 17 extends rearwardly through and is slidably mounted in an opening 19 in the apex of the bowl 10 and has its outer end disposed in a Chamber 20 which is formed in and extends through the enlarged portion 13 of the shank 11. The central portion'of shaft 17 is enlargedand cut to form a pinion or gear 21 which is adapted to mesh with and be insure the separation of the ice cream from the bowl by imparting axial movement to the scraper besides the usual rotary movement. The means for accomplishing this axial movement comprises a pair of studs 30 and 31 -which are integrally formed with the outer face of pinion 21 and the inner end of plug 27 respectively. These' studs have inclined surfaces 30a and 31a respectively, which are adapted to coactwith each other when the studs are brought into engagementiwith each other to Shift the pinion, shaft, andV scraper i axially and thus impart an outward movement to the ice cream in the bowl. These studs are disposed at distancesa little greater than 180o apart, as shown by dotted lines in Fig. 1, so that they will not engag'e each other and cause the axial movement of the scraper until after the hla'des 15 and 16 have completely encircled the inner surface of the bowl. A coil spring 32 vis mounted on shaft 17 and has one end abutting against the bowl adj acenti opening 19 and at its other end disposed in a socket 33 formed in p-inion 21. This spring is adapted to retract the shaft and scraper to their normal position when the studs 30 and 31 are out of engagement.

Raclebar 23 extends beneath handle-shank 11 and is pivotally connected at its distal end to one end of an angular horizontally disposed finger-lever 35. This lever is removably pivoted by a stud 36 which extends through a laterally offset lug 37 which is integrally formed with handle-shank 11. The stud is provided at its upper end with a washer and a pin for holding the leVer in pivoted relation to the handle. The lever comprises a backward-ly and outwardly ex.- tending finger piece 410. A eoil spring 41 is disposed in suitable pockets forined in the contiguous faces of the lever and lug respectvely and the pressure .of the spring is .applied to retract the lever and part-s operated thereby including the scraper. A pin .74:8 ,extends through handle-shank 11 and is adapted to be engaged by a cooperating stop 44 on the lever to limit the movement of the latter in one directionand causes the lever to be 'he'lcl' in vits normal position by the spring.

The invent'ion exemplifies an ice .cream dis'her .of new and improved vconstruction inv which prov'is'ion is made 'for ;sliifting the scraper axia'lly relatively tothe bowl besides rotati'ngfithe scraper,so as :to insure the separation of the ice cream fromzthe bowl.
